3 Claims.

This invention relates to engine mounting, and ignition wiring, andparticularly to a. combination or unit in which an engine. mountoperates as a shield for the engine ignition wiring.

An object of the invention is to provide a compact, lightweight mountingfor an engine, as of the radial type, which also constitutes a manifoldto retain and to-actlas a shield for the engine ignition wires, in anarrangement which, conserves space and weight where such factors arecritical, as in aircraft.

Another object is to provide an engine mount, of the type indicated,which may operate in any one-or combination of capacities; as aradioshield, a liquid shield, and as a protective shield generally forthe ignition wiring.

Another object is to provide means whereby a unit of the type indicatedmay be conveniently assembled and serviced, and the locating andattaching of wires facilitated.

Another object is to greatly simplify an engine and wiring assembly, notonly from the standpoint of appearance, but also in the matter ofrendering more accessible all parts of the engine heretofore obstructedby the wiring.

Another object is to provide a combination of the above-indicatedcharacter which is simple and durable in construction, economical tomanufacture, and effective in its operation.

The above and other objects and features of the invention will appearmore fully hereinafter from a consideration of the following descriptiontaken in connection with the accompanying drawings wherein oneembodiment of the invention is illustrated by way of example.

In the drawings:

Figure l is a view, in side elevation, of a unit constructed inaccordance with the invention, with the wiring shown in full lines andthe mount and other parts indicated partially by full lines andpartially by broken lines; and

Figure 2 is a rear elevation of the structure of Figure 1, as viewedfrom the right thereof, having corresponding full and broken lines.

Referring to the drawings, a combined engine mount and ignition wiringmanifold it! comprises, in the position illustrated, a frame I 2including a top tube I4 of inverted substantially U-shape, as seen inFigure 2, having a top central rear inlet opening H3. A lower tube E8,of upright substantially U-shape, cooperates with the top tube M, as bybeing welded thereto at positions 20, to form an upright-plane ring-likestructure 22.

Legs 24 of the top tube I4, which are substantially tangent to the ring22, in this instance 2 extend downwardly and forwardly from the ring. A,horizontal bottom tube 28- is disposed at each side. of themountextending rearwardly from the corresponding leg, 24.

Tubes 28., as. shown,.extend diagonal y at Corresponding angles from therear of the ring 22' adjacent to each end of the horizontal diameter ofthe ring to points Bil. rearwardly of the ring on the correspondinghorizontal side tubes 26. A rear tube 32 is disposed between, and isweld connected to, the horizontal tubes 26 adjacent to the intersectionsof the latter with the diagonal tubes 28. Reinforcing means. or gussetsi 34w subtend angles between certain of the frame tubes.

Upright tubular feet 36, of less diameter than, and extending throughthe horizontal side tubes 26 adjacent to the front and rear endsthereof, extend for short distances above and below the side tubes 26 toact as bases for mounting bolts 38, Figure l, to prevent crushing of thetubes 26 by the bolts.

Brackets 4E2, integral with the ring 22 for supporting an engine, aredisposed, in this example, substantially in quadrature with each other,with one in each quarter of the ring relative to its vertical andhorizontal diameters.

Outlet portions 42 from the ring 22 are provided one for each enginespark plug, and, as shown in this instance, are in the form of screwthreaded nipples each adapted to receive an end coupling 44 of anarmored flexible conduit 45. The portions 42 may, in other instances beof simple round section or bead formation to avoid sharp edges.

A box 48, secured to the ring 22 rearwardly of, and communicating with,the inlet opening [5, is provided with a rear door 50, and with flexiblemetal conduits 52 communicating from inner ends 53 of the conduits with,and projecting oppositely from, the ends of the box toward the sides 26away from the ring 22. Small cylindrical terminal casings 55 areprovided at outer ends 5? of the conduits 52.

An ignition circuit 54, comprising a battery 56, Figure 2, a solenoid58, an ignition switch 66], and magnetos 52 and 64, also includesinsulated ignition wiring 65, entirely around the ring 22 therein,having portions within conduits 68 entering the ring through theflexible conduits 52, the box 48 and the inlet l6, and portions "mextending from the ring through the outlets 42.

The device, as above set forth, is radio shielded, but may also beadvantageously utilized, where radio shielding is not desired, as byrounding the 3 outlets 42, as above indicated, and omitting parts, suchas the flexible metal conduits 4B, 52 and 68.

Although only one embodiment has been illustrated and described, andothers sufficiently indicated, various changes in the form and relativearrangements of the parts may be made to suit requirements.

What is claimed is:

1. A combined engine mount and ignition wiring manifold, comprising, aframe including a top tube of inverted substantially U-shape having anupper inlet opening, a lower tube of upright substantially U-shapecooperating with the top tube to form an upright-plane ring-likestructure the legs of the top tube being substantially tangent to thering and extending downwardly from the ring, a horizontal bottom tube ateach side of the mount extending rearwardly from the lower end of thecorresponding downwardly extending leg, tubes extending diagonally fromthe rear of the ring adjacent to each end of the horizontal diameter ofthe ring to points rearwardly of the ring on the correspondinghorizontal side tubes, a rear tube between and connected to thehorizontal tubes adjacent to the intersections of the latter with thediagonal tubes, reinforcing means subtending angles between certain ofthe frame tubes, upright tubular feet extending through the horizontalside tubes adjacent to the front and rear ends thereof to positionsabove and below the horizontal side tubes, brackets on the ring formounting an engine, and a plurality of outlet openings spaced along theouter circumference of said ring.

2. A combined engine mount and wiring manifold, comprising, a tubularupright-plane ring having an upper inlet opening, a tubularsubstantially horizontal frame below and extending lengthwise forwardlyfrom the ring plane for a given distance and rearwardly from the ringplane for a greater distance, tubular legs at each side of the mountextending forwardly and other tubular legs extending rearwardly from thering adjacent to its horizontal median plane to the side tubes adjacentto the side tube ends, upright tubular feet extending through, above andbelow the side tubes adjacent to said ends, brackets on the ring formounting an engine, and a plurality of outlet openings along the outercircumference of said ring.

3. A combined engine mount and. wiring manifold, comprising, a tubularupright-plane ring having an inlet opening, a tubular substantiallyhorizontal frame below and extending forwardly and rearwardly from theplane given distances, respectively, tubular legs extending forwardlyand downwardly from the ring to the frame, brackets on the ring formounting an engine, and an outlet from the ring for each spark plug.
